HEADSTOCK FOR LATHES.

Original application filed October 27, 1924, Serial No. 746,005. Divided and this application filed April This invention relates to new and useful improvements in headstocks for lathes, and is a division of my application, Serial No. 746,005, filed October -27th, 199A.

It is the principal object of this invention to mount the spindle bearings in the headstock, where they are completely enclosed and protected from dust and dirt. All objectionable overhang is thereby eliminated.

It is another object of my invention to provide in the headstock cover plate, handplates which may be readily removed to permit an easy adjustment of the spindle bearings.

In the accompanying drawings illustrating my invention, Figure 1 is a longitudinal, sectional view taken through the center of the spindle of my improved lathe headstoclt. Figure 2 is a side view of the latter. And Figure 3 is a cross sectional view taken on the line 3-3 of Figure 1.

Referring 'to the accompanying drawings for a detailed d-escription of my invention, the numeral 1 designates a headstock casing which is preferably of the bowl type to give exceptional strength and rigidity. This headsto'ck casing is provided with a cover plate 2 beneath which, within the casing and forming portions thereof, are bosses 3 and et which provide seats for journal bearings 5 and 6 respectively for a spindle 7 of lthe usual engine lathe type. The spindie bearings are thus brought within the headstock casing by these bosses 3 and 4 to eliminate the objectionable' overhang and 'to protect the bearings from dust and dirt.

To the bosses 3 and L1, which have caps 8, easy access may be had for oiling and the adjustment of screws, through removable hand plates Sa in the cover plate 2. (See Figures 2 and 3.) rlfhese hand plates 8 permit access to the journal bearings for oiling and the adjustment of cap screws without the necessity of 'removing the cover plate 2.

Splined to the spindle 7 by means of squared portions 12 thereon, is a clutch member 13 of the double jaw type. This clutch member 13 is adapted to clutch the spindle to either one of two clutch members 14C and 15 secured to gears 16 and 17 re- Serial No. 20,989.

iVhen the clutch member 13 ismoved to the f right as shown in Figure 1, the spindle 7 will be' driven from the gear 17; but when moved to the left, the spindle will be driven from either the gear 16 or the gear 20. (See Figure 1.)

The casing 1 is provided with a sliding pin 21 adapted to enter a pocket 22 in the gear 1T to prevent its rotation when desired.

rlhe `spindle hearing bosses 3 and t project inwardly from' the side 'Walls of the casing to support the bearings 5 and 6 in suchv a manner as to eliminate overhang. rlfhese bearings have flanged ends which project around the ends of the bosses to aid in firmly anchoring the bearings in the bosses and to assist in preventing the entrance of dust and dirt to them.

`Having described my invention, I claim:

1. A headstock for lathes, comprising a casing, a spindle therein, means for driving the spindle, bosses formed on the side walls of the casing` and extending inwardly therefrom, flanged journal bearings fitted to said bosses within the casing, and removable cover means directly over said bosses to permit ready access to the bearings.

Q. A headstock for lathes, comprising a casing, a spindle therein, means for driving the spindle provided within the casing, a cover plate for the casing, and removable portions within said cover plate over the bearings.

A headstock for lathes, comprising a casing, a' spindle therein, means for driving the spindle, bearing bosses formed within the casing, journal bearings for the spindle mounted. within said bosses, and removable hand plates Ain the cover plate over said journalv bearings. 1

In witness whereof I have hereunto set my hand this 3d day of April, 1925.
